ACL Femur Cyst Very Rare Presentation - A Case Report

A ganglion cyst is just an accumulation of gelatinous fluid in thick covering that develops from the capsules around tendons or joints . The cause is unknown; however, several suggestions have been put forth, including ectopic tissue development, synovial herniation, and trauma . The clinical symptoms differ based on the location. Management techniques such as non-operative, computed tomography-guided aspiration, open debridement, arthroscopic debridement, and decompression are advised.

Here, we report a 32-year-old man who had no history of severe trauma but had been complaining of knee flexion pain for the previous 3 years. There is no clinical laxity, and no additional injuries were observed. The patient had a magnetic resonance imaging (MRI) and an X-ray conducted. X-ray appears normal. The femur foot print location has a big cystic lesion seen on the MRI, located behind the ACL. No other anomalies are found.

Femoral ganglion cysts are frequently missed but can be diagnosed with the use of a clinical examination and a link between the clinical findings and MRI. The pain is reduced with arthroscopic cyst decompression.
